I think the documentation for the (k) flag is (for once) reasonably
clear and accurate:
k If name refers to an associative array, substitute the keys
(element names) rather than the values of the elements. Used
with subscripts (including ordinary arrays), force indices or
keys to be substituted even if the subscript form refers to val-
ues. However, this flag may not be combined with subscript
ranges.
This means you can use it with normal arrays, but only with individual
indices. So:
% print ${(k)files[(r)foo.c]}
2
but it doesn't work with a subscript nor with a range nor with the *
and @ subscripts (which are special ranges).
That doesn't mean this is convenient...
